Portable drum sound simulator generating multiple sounds

Abstract

A portable drum sound simulator is provided which includes an electronic drum sound generating means capable of generating a plurality of drum-like sound outputs and energizable in response to electrical trigger signals. Also included is a tone pitch varying means which varies by a plurality of steps the tone pitch of the drum-like sound outputs. A switch allows a user to select a desired drum-like sound output and another switch allows a user to select a desired tone pitch for the drum-like sound output. These two switches are each mounted on a respective drumstick each of which also includes a normally open electrical switch. These electrical switches are connected to the drum sound generating means and when closed causes a trigger circuit to develop a trigger signal which energizes the drum sound generating means so as to generate the drum-like sound output.

What is claimed is: 
     
       1. A portable drum sound simulator comprising: a portable enclosure having therein drum sound generating means comprising an electronic circuit having a power source and energizable in response to momentary electrical trigger signals for generating two different audible drum-like sound outputs each in response to a corresponding trigger signal;   a sound select switch connected to the electronic circuit and having means for selectively selecting which said drum-like sound output the drum sound generating means generates;   tone pitch varying means connected in the electronic circuit for varying the tone pitch of generated drum-like sound outputs;   a tone select switch connected to the tone pitch varying means comprising means for selecting a higher tone pitch than one previously set, means for selecting a lower tone pitch than one previously set and means for maintaining a selected tone pitch;   two normally open independently activated switches connected to the electronic circuit and momentarily closable for developing the momentary electrical trigger signals for independently effecting energizing of the drum sound generating means when momentarily closed and generating the drum-like sound outputs; and   two drumsticks each having a corresponding one of the two independently activated switches and movable in a striking motion in any desired direction at an accelerated velocity and decelerated at a certain rate momentarily at will while moving in said any direction for effectively generating the electrical trigger signals, each said independently activated switch having means for detecting momentary deceleration of the corresponding drumstick and effecting momentary closing of the corresponding switch in response to the detection of the momentary decelerations and effecting generating of the momentary electrical trigger signals.   
     
     
       2. A portable drum sound simulator according to claim 1, wherein said sound select switch comprises two normally open contacts each corresponding to a respective drum-like sound output and each alternatively closable for selecting a corresponding drum-like sound output. 
     
     
       3. A portable drum sound simulator according to claim 1, wherein said tone select switch includes a normally open contact closable for selecting a higher tone pitch than one previously set and another normally open contact closable for selecting a lower tone pitch than one previously set. 
     
     
       4. A portable drum sound simulator according to claim 1, wherein said drum sound generating means comprises a random noise generator generating a signal representing random noise and means for envelope and amplitude shaping the signal generated by the random noise generator for generating audible drum-like sound outputs. 
     
     
       5. A portable drum sound simulator according to claim 1, wherein said drum sound generating means generates two additional drum-like sound outputs and said sound select switch includes means for selectively selecting which of the two additional drum-like sound outputs the drum sound generating means generates. 
     
     
       6. A portable drum sound simulator according to claim 1, wherein said tone pitch varying means comprises means for controlling the time period of drum sound generation for varying the tone pitch of generated drum-like sound outputs as a function of the time period of drum sound generation. 
     
     
       7. A portable drum sound simulator according to claim 1, wherein said power source is a battery. 
     
     
       8. A portable drum sound simulator according to claim 1, wherein one of said drumsticks has mounted thereon said tone select switch and the other of said drumsticks has mounted thereon said sound select switch. 
     
     
       9. A portable drum sound simulator according to claim 1, wherein said drum sound simulator includes means for suspending the simulator on a user thereof.
